I've been asked to restore a German Gramophone and Typewriter type 6. It's the second one from the bottom in this gorgeous picture:

The list of things to do is quite impressive:
- Motor Board and turnplate: Rust removal, polish and nickel plating.
- Turnplate: Install new 100% wool green felt.
- Brake:Rust removal, nickel plating and new brake pad.
- Speed regulation knob: Make a replica. Nickel plated.
- Repair winding shaft hole: Recreate moulding in wood and close holes.
- Bottom mouldings: Recreate missing moulding in wood.
- Turntable shaft: Repair missing threaded part.
- Record holder: Replicate the missing nickel-plated record holder.
- Screws:Replicate missing ¼ 24TPI round head screws. Find suitable wood screws attaching the motorboard to the case.
- Wood case: Repair broken screw holes.
- Speed Governor: Replace springs.
- Unwinding spring: Replace broken spring.
- Fiber gear: Replace 144 teeth fiber gear.
- Mainspring: Relube mainspring and check the weird rivet that holds it. Replace spring if necessary.
- Motor: In depth clean, rust removal and tune up.

Upon arrival, I carefully disassembled it, labeled and started organizing the restoration.

I disassembled also the fiber gear and you can see the heroic fixing attempt that someone did in the past!

I'll be curious to see what you will do with the fibre gear. :geek:

Only some minutes today to work on this so I started to study the bottom profile and check if I have the suitable router bits.

Also started cleaning the damaged part of the upper profile.

I've just completed a replacement centre spindle with thread on my Style 11 single spring motor which has many similarities. Took me 3 attempts to get the clearances correct to stop it rumbling, but have got there in the end. Used an M10 steel bolt as my metal stock bar. Square cross-section leather shoe laces for the governor pads (soaked in oil for a new days). Lovely project. Envious!
